As a long standing partner to the Corrugated Industry ,zhuzhou mingri cemented carbide co. ltd ,manufactures Corrugated Slitting Knives for word renowned primary Corrugated Processing machines such as Agnati, BHS, Fosber, Gopfert, Isowa, Marquip, Mitsibishi, Peters, TCY, Xiexu, LMC, K & Machinery.



Tungsten carbide blade is mainly used for cutting paper in printing industry
tungsten carbide knife products require high precision, no glitches, maximum abrasion resistance.
we are using HIP sintered and fine grinding, polishing plating to reduce frictions when cutting, improved the accuracy and speed slitting greatly, tool life extended .



Corrugated Slitting Knives are consistently produced to the highest ISO9001 standards .


Corrugator slitter blade is made of ultra-fine tungsten carbide powder and cobalt powder pressed into sintering, is the best choice for cutting corrugated cardboard (3/5/7 layer) in the carton manufacturing industry. Ultra-specular (maximum surface roughness of .025μm) prevents film build-up on the blade for cleaner, more precise cuts.

Corrugated Slitting Knife can be accepted to work in harsh environments, so that product strength is greatly improved should not be damaged when used, the high-precision m-class special equipment production and processing, to ensure that the flatness of the product reached the slitting board does not fall edge shape, meet All kinds of cardboard cutting requirements.

2.Too frequent grinding; the grinding time is too long, or the grinding pressure is too high.

Q4. Why the edge of corrugated boards cut by knives with burr and dent ?

1.Please check the cutting edge of your blades. Is the cutting edge keen enough?
2.The corrugated board is too wet.

Q5. Why the knife break ?

1.Improper assembly(e.g. deformed flange plate; improper screwing)will cause the quick break of blades. Any improper touch of the blades is strictly prohibited during the working.
2.Unstable swing grinding wheels break the knives, please check the bearing of grinding wheels.
3.Improper touch or strike with other hard things.
4.Accident collision of knives

Q6. Why chips on the cutting edge after the grinding ?

1.Unstable swing grinding wheels may cause this problem, even break the knives.
2.The strike of hard things may cause the chips on the cutting edge.

Q7. Why the edge of corrugated board is not straight.

Unmatched strength of the knives for the corrugated board with high density.
